To a solution of 4-[2-amino-4-(4-methoxyphenyl)-1,3-thiazol-5-yl]-2-pyridylamine (0.40 g, 1.4 mmol) and 4-dimethylaminopyridine (0.055 g, 0.45 mmol) in N,N-dimethylacetamide (10 mL) was added acetyl chloride (0.3 mL, 4.2 mmol), and the mixture was stirred for 14 hours at 70° C. An aqueous sodium hydrogen carbonate solution was poured into the reaction mixture, and extracted with ethyl acetate. The extracts were washed with brine, then, dried and concentrated. The crude crystal was recrystallized from ethanol to obtain a title compound (0.30 g, yield 58%).
